First of all you need to remember that the rules for adding and subtracting fractions are the same and the rules for multiplying and dividing decimals are the same. I grouped "add and subtract" and "multiply and divide" together for this very reason. Another way to remember this is that adding and subtracting are always connected and multiplying and dividing are always connected. For example, 2+3=5 and 5-3=2 AND 3x4=12 and 12/4=3.
